A 0.181-kg ball has an elastic, head-on collision with a second ball that is initially at rest. The second ball moves off with half of the original speed of the first ball.
a) What is the mass of the second ball?
b) What fraction of the original kinetic energy (∆K/K) is transferred to the second ball?
